Struct PrivateKey 

pub struct PrivateKey(/* private fields */);

Private Ed25519 key used for digital signatures.

Implementations

impl PrivateKey

pub fn new() -> Self

Generates a new private key using the system’s random number generator (CSPRNG) as a seed.

pub fn from_bytes(bytes: &[u8; 32]) -> Self

Create a PrivateKey from its raw bytes representation.

pub fn as_bytes(&self) -> &[u8; 32]

Bytes of the private key.

pub fn to_hex(&self) -> String

Convert the private key to a hex string.

pub fn public_key(&self) -> PublicKey

Returns public key using this private counterpart.

pub fn sign(&self, bytes: &[u8]) -> Signature

Sign the provided bytestring using this private key returning a digital signature.
